El Kansera Dam

It lies northwest of the city of Meknes and about 20 kilometres (12 mi) south of Sidi Slimane, upstream from Dar bel Amri.

[3] The site of the dam was a deep, narrow gorge that the Beth had cut through the limestone bordering on the lowlands.

Winter floods of the Beth had created large merdjas on the Sebou's left bank, which would be ideal for cultivation once irrigation water was available.

[4] At first the colonial agriculture and public works administrations opposed construction of this and other dams, but the main settlers, led by Gaston Lebault, pushed the project forward.

It would control flooding of the Beht and irrigate 30,000 hectares (74,000 acres) of fertile land in the Rharb plain.

The job was complicated by the difficulty of conducting deep excavation near the foundation and problems with making the new concrete bond to the old.
